Capacitor Break In Box

The capacitor break in box is a small project I made to help break in, or burn in, capacitors for use in guitar amplifiers and other projects. I like to call it the Capacitor BIB. This can be a helpful tool if you’re building guitar amplifiers.

Using the Capacitor Break In Box

I let the caps run with electricity for about 100 hours, and then I install them in the amp. I only leave the box on while I’m awake, probably because I’m a little paranoid. So it takes me about a week for each set. The end of the clamp opposite the AC leads has a spring loaded screw. As a result I can pressure load the caps and it keeps everything pretty simple. However you build your capacitor break in box, always keep safety in mind first.
